LINE is the main messenger in Japan, Thailand and Taiwan. If you sell into those markets, a LINE Official Account is usually where your customers already are.

The channel connects to a LINE Messaging API channel, which you create in the LINE Developers Console and attach to your Official Account.

What you need

From the LINE Developers Console, on your Messaging API channel:

  • the Channel ID
  • the Channel Secret
  • a Channel Access Token (long-lived)

Steps

  1. Go to Settings → Inboxes, add an inbox, and choose LINE.
  2. Enter a channel name for your own dashboard, then the Channel ID, Channel Secret and Channel Access Token.
  3. Finish. Open the channel's Configuration tab and copy the Callback URL.
  4. In the LINE Developers Console, set that URL as the channel's Webhook URL and switch "Use webhook" on.
  5. In the same console, switch off the auto-reply and greeting messages if you want your agents to be the ones replying. LINE answers on the account's behalf by default, and those replies do not come from Lynomia Chat.

Limits

  • A LINE channel cannot start a conversation with someone who has not added the Official Account.
  • LINE's own auto-replies are configured in LINE, not here, and they will talk over your agents until you turn them off.
  • Rich message types — stickers, location, LINE-specific templates — arrive as what LINE sends; an agent replies with text and attachments.

Who can do this

Administrators.

If it does not work

Nothing arrives. Check the webhook in the LINE Developers Console: the URL must be the one on the Configuration tab, "Use webhook" must be on, and LINE's own "Verify" button must report success.

Replies fail. The Channel Access Token has expired or was issued for a different channel. Issue a new long-lived token and update the channel's settings.
